NOTES:

2. Tested at AVDD = 20V.

3. Simulated and Determined via Design and NOT Directly Tested.

4. Simulated Maximum Current Draw when Programming EEPROM is 23mA, should be considered when designing Power Supply.

5. A Typical Current of 20µA is Calculated using the AVDD = 10V and RSET = 24.9k

Ω. Reference “RSET Resistor” on page 5.

6. Simulated and Designed According to I2C Specifications.

7. Parts are 100% tested at +25°C. Over-temperature limits established by characterization and are not production tested.

Electrical Specifications

Test Conditions: VDD = 3V, AVDD = 10V, OUT = 5V, RSET = 24.9kΩ; Unless Otherwise Specified.

Typicals are at TA = +25°C (Continued)
